Apparent wind
This provides an offset calibration in degrees to compensate for
any mechanical misalignment between the masthead unit and the
center line of the vessel.
To check the masthead unit alignment error we recommend you
use the following method which involves a sailing trial.
Sail on a starboard tack on a close hauled course and record the
wind angle, then repeat the process on a port tack. Divide the
difference between the two recorded numbers and enter this as the
wind angle offset.
33º
27º
WIND
Starboard Tack
Port Tack
Starboard tack = 33º
Port tack = 27º
Difference: 33º - 27º = 6º
Offset: 6º/2 = -3º
If the starboard apparent wind angle is greater than the port angle
then divide the difference by 2 and enter this as a negative offset.
If the port angle is greater than the starboard then divide the
difference by 2 and enter this as a positive offset.
